LFP Battery in Kerala: LiFePO4 for Inverters and Solar
LFP (lithium iron phosphate) batteries are replacing lead-acid in many Kerala homes and shops. See how they compare and which Earth Power LFP battery suits your inverter.
What is an LFP battery?
LFP stands for lithium iron phosphate (LiFePO4), a lithium-ion chemistry widely used for home inverters, UPS and solar storage. It is chemically stable and designed for repeated charge and discharge cycles.
LFP vs lead-acid (tubular) batteries
- Weight: LFP is much lighter. Our 12.8V 100Ah Earth Power battery weighs about 13 kg.
- Maintenance: no distilled-water topping.
- Usable capacity: lead-acid batteries are normally kept at a shallow discharge to protect their life; LFP lets you use more of the rated capacity.
- Cycle life: LFP generally lasts many more charge cycles, which is why the lifetime cost can be lower.
- Upfront cost: LFP costs more to buy.
- Inverter settings: many inverters need a lithium charging profile or setting. Check before switching.

As a rough guide, a 2.56 kWh battery running a 500 W load lasts about 4 to 5 hours after losses. Actual runtime depends on your inverter and load.
Handling and safety
- Keep the battery away from flame, excess heat and conductive debris.
- Prevent short circuits and reverse polarity; use correctly rated cables and protection.
- Do not use a battery that is damaged, swollen, leaking or unusually hot.
- Have it installed and commissioned by qualified personnel.
Frequently asked questions
Is an LFP battery safe for home use?
LFP is one of the more thermally stable lithium chemistries and every Earth Power battery has a BMS. It must still be installed correctly with proper cables and protection.
Can I replace my lead-acid battery with LFP?
Often yes, if your inverter can charge lithium batteries at the right voltage. Send us your inverter model and we will check.
How long does an LFP battery last?
Earth Power gives a 5-year warranty on every model. Real life depends on how deeply and how often you cycle it.
Which LFP battery size do I need?
Divide the battery's kWh by your load in kW for a rough runtime. Tell us your load and backup hours and we will suggest a size.
